“As I said before, if we’d have been more clinical in front of goal we possibly could have had three wins,” said Lampard.

“The competition is there and that’s the challenge for the strikers.

“I’ve got no problems with their attitude and training. We work hard on the training ground as a team to create and also to finish. I used to love practising my finishing in training.

“What I have got is great attitude in the three strikers. But others in the squad also always want to stay out, want to work harder.

“Tammy’s goal goes in off the post against United, different story for him, different story for the game. But we can’t get too down about that, we’ve got to stay positive and it will come.

“We’ve got some great attacking players here and it will come.”

Belgium striker Batshuayi scored twice in Chelsea development squad’s 3-0 win over Liverpool earlier this week, but is still working towards full match fitness.

Lampard praised the 25-year-old’s showing in the reserves, insisting Chelsea need him to contribute at first team level this season.

“I thought it was a good performance and he got the fitness work he needed out of the game,” said Lampard.

“It was two good goals; two very good finishes. He worked hard and that’s exactly what the game was for.

“We need Michy, we need the competition up front. I thought the team performance was really good.”

Chelsea will head to Norwich on Saturday with Lampard not only hoping his strikers come good in front of goal in the league, but also that N’Golo Kante can shake off an ankle sprain.

Antonio Rudiger is not ready to feature this weekend as he closes in on a return after long-term knee trouble, but could be ready for the Stamford Bridge league match against Sheffield United on August 31.

Pedro missed training earlier in the week but was rested after a hectic fixture schedule and is expected to be fit to take on the Canaries on Saturday.

“Kante has got an injury he has carried all week, so we’ll assess that over the next 24 hours,” said Lampard.

“Rudiger’s not fit yet, hopefully for next week. That’s the only changes from where we were last week.”

Asked if Pedro had an injury issue after missing training earlier in the week, Lampard said: “That was because we had, as we know, a busy week and Pedro contributed a lot physically, he had a couple of small aches.
